The Latin America and the Caribbean Open Data Conference (CONDATOS) was first launched in Montevideo (Uruguay) in 2013 as an initiative of the Uruguayan Government to convene key players that could help coordinate regional efforts around Open Data. That first conference was funded by the World Bank, the Inter-American Development Bank, the International Development Research Centre (IDRC), The Economic Commission of the United Nations for Latin America and the Caribbean (CEPAL) and the Organization of American States (OAS). Although CONDATOS focuses on Government agencies, since its first edition in 2013, it has always been organized in tandem with an “unconference” event called Abrelatam, whose goal is to attract regional non-government actors that are interested in Open Data. Both CONDATOS and Abrelatam started as exploratory and emerging efforts that have been evolving and helping shape the Open Data landscape in the region. In March 2015, some key actors met in Santiago de Chile to discuss these issues and do some planning for the third edition of CONDATOS, which was held in that same city in September 2015. This planning meeting provided an opportunity to discuss the possibility of doing some evaluation of the Conference. In June 2015 it was finally decided that a U-FE approach was going to be undertaken on CONDATOS under the coordination of Fundación Avina and in collaboration of DECI-2. U-FE usually requires extensive interaction between the evaluator and the primary users, especially during the initial phases that are about designing the evaluation system. Therefore, conducting U-FE in a short timeline and with little opportunity for the evaluator to engage the primary users face-to-face did not seem to be a good idea. However, the CONDATOS experience suggests that under certain conditions, it is possible to do U-FE within such constraints.
